This is trivial. Redirect everything to a virtual table, have it
rewrite everything local to the department server, except have a more
specific, earlier pattern for root. It is a ten line configuration
(give or take). I haven't actually tried it but I see no reason it
wouldn't work -- other similar things work for me.

Perhaps you should have asked others for help -- what you wanted isn't
a hard thing to do.

It is pretty damn flexible. The problem is that sometimes you need to
"think the way postfix thinks", which is a bit different from the way
you approach problems with sendmail.
